ptfe coated fiberglass seal

PTFE Coated Fiberglass Cover Fiberglass Core Tadpole Gasket is a flexible sealing solution designed for thermal doors, oven covers, dampers, ducts, panel joints, enclosures and applications exposed to temperature changes or chemical environments. The gasket combines a PTFE-coated woven fiberglass cover with a fiberglass rope core. The PTFE coating provides a smooth, chemically resistant outer surface, while the fiberglass core forms the resilient sealing bulb and allows the gasket to compress and conform to uneven mating surfaces. Unlike Tadpole Gaskets developed primarily for extreme high-temperature service, this construction is particularly useful when chemical resistance, flexibility, thermal shock resistance and low-temperature performance are important considerations. BSTFLEX can manufacture custom PTFE coated fiberglass tadpole gaskets in different bulb diameters, tail widths, lengths and profile configurations according to drawings, samples and application requirements.

Aluminized Fiberglass Tadpole Gasket is a flexible thermal sealing solution designed for oven doors, heating equipment, thermal enclosures, access panels, covers and other industrial applications where heat reflection and reliable compression sealing are required. The gasket combines a woven fiberglass cover with an aluminized surface and a flexible internal core. The reflective outer layer helps redirect radiant heat away from the gasket surface, while the internal core provides the body and resilience required for the tadpole sealing profile. Depending on the application, the gasket can be manufactured with a galvanized wire core or hollow flexible core. The bulb compresses against the mating surface to create the primary seal, while the tail provides an attachment area for mounting to doors, frames, panels or equipment structures. BSTFLEX manufactures custom aluminized fiberglass tadpole gaskets in different bulb diameters, tail dimensions, lengths, core constructions and profiles. Drawings, samples and application specifications can be used for OEM and replacement gasket development.
